Colorectal Cancer
Colorectal Cancer Facts
Colorectal (colon and rectum) cancer is the second most common
cancer in the United States. About 150,000 new cases are
diagnosed each year. Most develop from polyps, growths that
originate in the mucous lining of the colon or rectum. These
grow slowly and can be detected by means of effective, easily
performed tests, making colorectal cancer one of the most
curable forms of cancer.
Colorectal Cancer Causes and Risk Factors
The cause of cancer of the colon and rectum isn't known, but
it's believed that the disease is associated with a diet high
in fat and low in fiber (roughage). Not surprisingly,
colorectal cancer is more common in Western countries, where
the diet tends to be highly refined, with less roughage.
People over age 50 are more susceptible, and African-American
men have a slightly higher risk. Anyone with a personal or
family history of colorectal cancer, polyps in the colon, or
ulcerative colitis is at particularly high risk and exposure
to asbestos has been identified as a risk factor.
Colorectal Cancer Symptoms
The most common symptom is bleeding with bowel movements.
Other symptoms include pain during bowel movements, change in
frequency of bowel habits, change in stools, abdominal pain or
swelling, fatigue, anemia, and weight loss.
Early Detection and Prevention of Colorectal Cancer
Colorectal cancer is very curable when found early and there
are several things you can do to lower your risks:
* Eat at least 25 to 30 grams of fiber a day.
* Eat lots of fruits and vegetables.
* Have a digital rectal examination every year after age 40.
* Have a stool blood test every year after age 50.
* Have a flexible sigmoidoscopy at age 50, and then, after two
normal examinations a year apart, every three to five years.
* If you are over 50 and notice blood in your stools, see your
doctor immediately.
